Detailsinfo

A vulnerability classified as problematic has been found in Arista EOS (version now known). Affected is some unknown processing of the component SNMP. The manipulation with an unknown input leads to a memory leak vulnerability. CWE is classifying the issue as CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. This is going to have an impact on availability. CVE summarizes:

On affected platforms running Arista EOS with SNMP configured, a specially crafted packet can cause a memory leak in the snmpd process. This may result in the snmpd processing being terminated (causing SNMP requests to time out until snmpd is automatically restarted) and potential memory resource exhaustion for other processes on the switch. The vulnerability does not have any confidentiality or integrity impacts to the system.

The weakness was released 04/13/2023. The advisory is shared for download at arista.com. This vulnerability is traded as CVE-2023-24511 since 01/24/2023. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1499.
